This bizarre distorted video was created with Slit-Scan Movie Maker, a Mac app that simulates slit-scan photography. Slit-scan is a photographic process in which a moving slit is placed between the camera and the subject, causing strange stretching and compression effects. Slit-scan was used to create the stretching Starship Enterprise warp effect for Star Trek: The Next Generation. It used to be a costly mechanical process, but can now be accomplished by software. Slit-Scan Movie Maker is by Trevor Alyn.
